The way the opening scene and the Ghost Train returns goes in Revenge of the Ghost Train.
One night at Canterlot.
Princess Yuna: (looking through the telescope)
Nyx: I'm glad Flash and Twilight let me spend the night with you guys.
Snowdrop: Me too, Nyx, Yuna, Can you see anything?
Dusty Crophopper: What do you see, Yuna?
Princess Yuna: I see a Shooting Star! (making her wish)
Princess Luna: (holding Prince Isamu) Yuna, Snowdrop, Nyx, Time for bed.
Hiro: You three better get ready.
Princess Luna: Or else The Ghost Trains will haunt you.
Princess Yuna: Do you think the Ghost Trains could be everywhere?
Princess Luna: Don't worry, Yuna.
Hiro: The Ghost Train Busters will come to the rescue.
Dusty Crophopper: That's right.
Princess Luna: What do you think of them, Snowdrop?
Snowdrop: Wow! Cool team!
Hiro: And amazing Ghost Train hunters.
Princess Yuna: (yawns) Goodnight, Mama, Goodnight, Papa.
Snowdrop: Goodnight, Luna, Goodnight, Hiro.
Princess Luna: (kisses Yuna and Snowdrop) Goodnight, My daughters.
Hiro: Pleasent dreams.
Princess Yuna and Snowdrop: (sleeping)
Dusty Crophopper: Isn't the night beautiful, Luna?
Princess Luna: Indeed it is, Dusty.
Hiro: And let's hope nothing goes wrong.
Princess Luna: Time for beddy bye, Isamu.
Prince Isamu: (laughs and yawns)
Princess Luna: (humming You'll Be in My Heart)
Prince Isamu: (falls asleep)
Princess Luna: (kisses Isamu on the forehead)
Somewhere at the viaduct.
Ghost Train: (whistles)
Then, Ghostbusters Theme Song begins.
